Problem 1: H AlCl3 ? + CH2Cl Problem 2: H FeBr3 ? + CH3CH2CH2Br
Problem 3: H HF + ? ? Problem 4: SO3H CH3CH2Br ? FeBr3 Problem 5: Show the mechanism for the Friedel-Crafts Alkylation of benzene and CH2Cl2 with SbCl5 catalyst.
Solutions Problem 1: H CH2 AlCl3 + CH2Cl + HCl Problem 2: CH3 H CCH3 FeBr3 + CH3CH2CH2Br + HBr
Problem 3: H HF + Problem 4: SO3H No Reaction, because the benzene ring is strongly deactivated. CH3CH2Br FeBr3
